ABSTRACT:
Circuitry for synthesizing an arbitrary clock signal with minimal jitter is provided. The circuitry of this invention selectively multiplexes a sequence of two different byte patterns into a serializer, which serializes the sequence and transmits it to receiver circuitry in the serial domain. The frequency of the synthesized clock transmitted by the serializer is a function of the serialized sequence and the frequency in which the serialized sequence is transmitted to the receiver circuitry. Thus, a desired clock frequency can be synthesized by manipulating the byte patterns and the sequence in which the bytes are serialized.
